Product Description
Lapua .338 Lap Mag Unprimed Brass Cases
Lapua .338 Lapua Magnum Brass Cases – Unprimed | Box of 100
Lapua .338 Lapua Magnum brass cases are widely regarded as the gold standard in precision reloading brass, trusted by long-range shooters, competition marksmen, and professional reloaders worldwide.
Manufactured in Finland to exceptionally strict tolerances, Lapua .338 Lap Mag brass delivers outstanding consistency, durability, and accuracy across multiple reloading cycles.
Precision Engineering for Long-Range Accuracy
Lapua cases are engineered with a hard, reinforced base, ensuring the primer pocket maintains perfect dimensions even after repeated firings. This results in reliable primer seating, improved ignition consistency, and extended case life.
The brass body is firm yet elastic, allowing smooth expansion and contraction during firing. This design improves case extraction, reduces stress on the brass, and maximizes reloadability—ideal for high-pressure magnum cartridges like the .338 Lapua Magnum.
Superior Neck & Shoulder Design
Lapua applies tight concentricity and uniform wall thickness, especially in the neck area, to ensure precise bullet alignment and seating. This minimizes bullet runout and prevents projectile movement during transport or handling.
The neck and shoulder are carefully annealed, allowing them to withstand multiple reloads while maintaining consistent neck tension—critical for extreme-range accuracy.
